FATIGUED DRIVING IN YOUNG AND OLDER ADULTS: THE EFFECTS OF AN AUTOMATED TRIVIA GAME
MetadataShow full item record
Implementing a secondary (dual) task, such as a trivia game, has been found to increase driving performance in tired young adult drivers. This study examined the effects of an interactive trivia game during monotonous simulated driving (MSD) on driving performance young and older adults. Participants completed measures of executive function prior to the simulated drive. Fatigue was induced through MSD, followed by a 10-min baseline drive. Next, participants engaged in a 10-min dual-task drive during which they were asked to answer questions from an automated trivia game. Driving performance was measured by how consistently the driver stayed in the center of the lane. Results indicated a significant difference in dual task cost between age groups. No evidence was found to support the hypothesis that a dual-task intervention would improve lane maintenance. Poorer scores of executive function were significantly associated with poorer driving performance during the dual task condition.
